Hello guys!

I need some help with an issue that arised after I replaced my GPU and CPU respectively.

The system boots up fine, but after playing i.e. Witcher 3 for some time, Windows BSODs, and the computer restarts. It also happened to me a few times while idle. Both parts are brand new out of the box.

Those are my current specs, everything is stock. nothing OC:

-Win 10 64-bit
-Asrock N68-GS4 FX
-Asus Radeon R9 380X 4GB GDDR5 (STRIX Gaming)
-AMD Athlon FX8350 Black Edition
-2x HyperX FURY DDR3 4GB 1600MHz CL10
-CHIEFTEC CTG-600-80P 600W PSU

THE BSODs give out different errors, I tried and replugged everything, and it seemed to work fine for a while, but then it crashed again after ~1 hour. I would myself suspect that the mobo is the culprit, as it's a pretty low end one, but on the other hand it should support the FX8350. Idle temps are at ~50 C CPU, and ~45 GPU, and ~58C CPU ~60 GPU on load.

This is an easy one. You put a 125w CPU into a motherboard that only supports 95w chips. Your motherboard's VRMs are overloaded and causing crashing any time you try to do something CPU intensive. Run Prime95 and you'll get the same issue.

You have one of two options:

1) Downclock and/or undervolt your current CPU until it no longer crashes.

2) Swap your CPU out for a 95w chip, which will have lower stock voltage and clocks, or fewer cores, such as the FX-8320e or FX-6300.

Ok that's theorizing, that it might be faulty, it can also be perfectly fine. Any suggestions how to pinpoint the issue without having other PSU on hand?

Ok, thank you. That's what I figured, so I already got a good deal on Asrock 970 Extreme 3 which should do fine, if I'm not mistaken?

If I paid enough attention, I would have gone for i5 from the start, yep :/

He might still have problems though. While the board can't handle the CPU at full load, it should be able to handle it under gaming load because gaming power, especially in 4-core games, should not surpass 95W. In addition, blue screens while idling would have nothing to do with the motherboard. I'm going to maybe put my money on it being that the cheap PSU is causing problems. And remember, a PSU doesn't just work or not work. Different hardware has different tolerance levels on how well it can handle instability, and a cheap PSU like that can actually degrade the lifespan of his new hardware.

Best course though, I suppose, is change the motherboard. If the problem persists, then perhaps look into a better PSU.
